The electrical potential of the cell body changes during an action potential from a negative potential of around -70 mV to a positive potential of +40 mV. The resting potential, however, remains constant.
The electric charge of the action potential is positive. This is made possible by the influx of positive sodium and potassium ions via ion channels.
It's milivolt (the unit that's used for membrane voltage)
Action Potential
Potential, ok well we all know it's a potential, but which one? Is it Action Potential, Synaptic Potential or Membrane Potential. Just saying Potential isn't saying much?
Action potential
The chemical gradient refers to the imbalance of substances across the membrane. The Electrical Gradient refers to the difference of charges between substances on different sides of the Membrane. The Electrochemical Gradient refers to the combination of the previous two gradients. The short answer is MEMBRANE POTENTIAL.
Resting potential and action potential are both names for the measure of electrical voltage within the membrane of a cell. Specifically, these terms are used in describing the transfer of information along neural pathways. Resting potential is a state where cells are at rest. However, if an electrical response or depolarization reaches threshold, then ion channels open, allowing sodium ions to rush into the membrane and increase the voltage measure, firing an action potential along the length of this membrane.
Action Potential
This is called action potential. Action potential is the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals.

Explosion of electrical activity
Electric Potential = Electrical Potential Energy/ Charge The measurement for electric potential is call the volt. Electrical Potential is often called voltage. Voltage or Electrical Potential = 0.5 Joules / .0001 Coloumb = 5000
When unlike charges are moved farther apart, they gain electrical potential energy. Electrical potential difference is the change in potential energy per coulomb of charge. Voltage is the common name for electrical potential difference and is measured in volts (V). Electrical energy depends on the amount of charge and voltage. Electrochemical cells, or batteries, are a common source of voltage. We use voltmeters to measure potential difference. :)
Action potential
It is probably called as action potential.

a voltage or electrical charge across the plasma membrane
Resting potential and action potential are both names for the measure of electrical voltage within the membrane of a cell. Specifically, these terms are used in describing the transfer of information along neural pathways. Resting potential is a state where cells are at rest. However, if an electrical response or depolarization reaches threshold, then ion channels open, allowing sodium ions to rush into the membrane and increase the voltage measure, firing an action potential along the length of this membrane.
